IMPROVED WINDOW-SCREEN.

Specification iirming part of Letters Patent No. 58,982, dated October 23, 1566.

To all whom it may concern.:

Be it known that we, EDWARD BUCKLIN, Jr., and SEDGEwIcK A. SUTTON, of North Providence, in the county of Providence and State ot' Rhode Island, have invented a new and useful Improvement in Window-Screens; and we do hereby declare that the following specification, taken in connection with the drawings making a part ot' the same, is a full, clear, and exact description thereof.

Figure 1 is an elevation ot a window with our screen covering the lower sash. Fig. 3 is a view of the extension-rail shown in Fig. I. Figs. 2 and 4 are modifications ot' the same.

'lhe purpose ot' our invention is to provide a more etiicient means for securing' the screen in the window-frame, so that by the sudden force ot' a draft ot' wind it shall not beliable to he blown from its place, but at the same time admitting ot' ready removal when desired.

Screens for windows the frames of which are designed to be held in place by the pressure against the side of the window-casing obtained from a spring have heretofore been employed; but the sudden opening ot' a door, occasioning an unusual draft of air through the open window, will frequently dislodge them.

In the accompanyingdrawings, A represents the window-trame, and B the sliding sash. O is a netting, commonly called a mosquito har, which is attached at the top and at the bottoni edges to the rails D D. These rails can be conveniently made in two parts, which parts are connected by the rightand-left screw-coupling E, so as to be capable of eX- tension lengthwise by turning such coupling; or, instead thereof, a single-acting screwcoup ling (E, Fig. 2) can be used for the same purposethat is to say, a coupling with a thread cut upon only one end of it, the other end having no thread, so as to admit of its turning freely in or around the end of the other porA tion of the rail, aceordin g as the socket is made in the rail or in the end ot' the coupling; and

also a button-head with a spindle, having a thread cut upon such spindle, and titting a socket with a corresponding thread in one. end ot' the rails E, Fig. 4, could also be employed with thc same result, which modifications would be equivalents for the means ex hihited in Figs. l and b.

It is evident that the degree of friction required to hold the mosquito bar in place against the force of a draft ot' air can be readily obtained by operating such screw in a direction to extend the length of the bar, and that also the mosquito-bar can be removed altogether from the window, or the netting rolled up around either bar, adjusting the screen to the opening of the sash as convenently as in any other screen of a similar kind.

It will be observed that whether the rails I) are increased or diminished in length by the rotation of the screw, the width of the screen O is increased or diminished in exactly the same proportion, so that whatever may he the width of the window to which the rails are adjusted, the screen will always completely till it, leaving no gaps for the admission ot' insects.

1What we claim as our invention, and destre to secure by Letters Patent, is-

Attaching the screen directly to two supporting-rails, I) and D', in such manner that the width ot' the screen may be increased or diminished in the same proportion as the length of the rails, as and t'or the purpose described.
